Seated BP was to be measured at every visit. Data after rescue medication was excluded. The patient first rested for at least 10 minutes in the seated position. Seated blood BP was determined from the mean of 3 replicated measurements obtained at least 1 minute apart. However, if the 3 consecutive seated BP readings were not within 8 mm Hg of each other, an additional 2 BP readings were to be obtained (total=5) and incorporated into the calculated mean for systolic BP and diastolic BP. For the initial BP recording, BP was measured in both arms. If the BP was higher in 1 arm, that arm was used for BP measurement. If there was no difference in BP measurements between arms, the dominant arm was used for all future BP measurements. All randomized participants who received at least 1 dose of study drug and who had nonmissing baseline and at least 1 postbaseline value during the double-blind treatment period were used for analysis. SD=standard deviation.

HbA1c was measured as percent of hemoglobin by a central laboratory. All randomized participants who received at least 1 dose of study drug and who had nonmissing baseline and at least 1 postbaseline value during the double-blind treatment period were used for analysis. SD=standard deviation.

Ambulatory blood pressure monitoring was performed twice during the study, at baseline and at the end of study, for a duration of 24-hrs each time. If the patient met the criteria for rescue due to hypertension, a second monitoring was performed prior to the first dose of rescue medication. Initiation of the 24-hr ambulatory blood pressure monitoring began between 6 and 11 am to ensure trough blood pressure measurements were obtained. Patients were instructed to withhold all medication on the morning of the study visit and to bring their medications to the visit with them.

All randomized participants who received at least 1 dose of study drug and who had nonmissing baseline and at least 1 postbaseline value during the double-blind treatment period were used for analysis.

Central laboratory serum uric acid levels will be determined at the Enrollment, Day -28, Day 1, and at Week 4, 8, 12, and 13 visits. All randomized participants who received at least 1 dose of study drug and who had nonmissing baseline and at least 1 postbaseline value during the double-blind treatment period were used for analysis.

Original Secondary Outcome Measures ICMJE (submitted: June 3, 2010)

Change from baseline in HbA1c [ Time Frame: Baseline and after 12 weeks ] [ Designated as safety issue: No ]

Number of Participants With Adverse Events (AEs), Hypoglycemic Events, Related AEs, Death as Outcome, Serious Adverse Events (SAEs), Related SAEs, Discontinuations Due to SAEs, Discontinuations Due to AEs, and Discontinuations Due to Hypoglycemic Events [ Time Frame: Day 1 of treatment to last dose plus 4 days for AEs and hypoglycemic events and plus 30 days for SAEs ] [ Designated as safety issue: Yes ]

AE=any new unfavorable symptom, sign, or disease or worsening of a preexisting condition that may not have a causal relationship with treatment. SAE=a medical event that at any dose results in death, persistent or significant disability/incapacity, or drug dependency/abuse; is life-threatening, an important medical event, or a congenital anomaly/birth defect; or requires or prolongs hospitalization. Related=having certain, probable, possible, or unknown relationship to study drug. Includes nonserious AEs with onset on or after the first date of double-blind treatment and on or prior to the last day of double-blind treatment plus 4 days and SAEs with onset on or after the first date of double-blind treatment and on or prior to the last day of double-blind treatment plus 30 days. Includes data after rescue. Only hypoglycemia reported as an SAE is included in AE/SAE categories. All reported hypoglycemia events within 4 days of last day of treatment are included as hypoglycemic events.

Number of Participants With Clinical Laboratory Results Meeting Criteria for Marked Abnormality [ Time Frame: Day 1 of treatment to last dose, plus 4 days ] [ Designated as safety issue: Yes ]

Laboratory abnormalities were evaluated based on laboratory values meeting predefined marked abnormality (MA) criteria. Includes data after the start date of double-blind treatment up to and including the last day of double-blind treatment plus 4 days. BUN=blood urea nitrogen; preRX=pretreatment; unspecif=unspecified; ULN=upper limit of normal. High total calcium= ≥1 mg/dL from ULN and ≥0.5 mg/dL from preRX value; high inorganic phosphorus= ≥5.6 mg/dL if age 17-65 years or ≥5.1 mg/dL if age ≥66 years.

The normality or abnormality of the ECG tracing, determined by the investigator, was summarized by normal or abnormal ECG tracing at Week 12 overall and at baseline. When the data at Week 12 were not available, the last observation before discontinuation of that patient was used for summary.

Supine BP was measured prior to standing BP. The patient was to rest in the supine position for at least 5 minutes prior to measurement of BP. Supine BP was determined from 3 replicate measurements obtained at least 1 minute apart. The average BP was determined from these 3 replicate measurements. The patient then stood for 2 to 3 minutes. After this time, BP was measured with the arm supported at the antecubital fossa at heart level.

Supine HR was measured prior to the standing HR. The patient was to rest in the supine position for at least 5 minutes prior to measurement of HR. Supine HR will be determined from 3 replicate measurements obtained at least 1 minute apart. The average HR was determined from these 3 replicate measurements and reported in the case report form. The patient then stood for 2 to 3 minutes. All measurements were to occur at least 10 hours after the last ingestion of caffeine, alcohol, or nicotine.

The purpose of this study is to learn whether dapagliflozin, after 12 weeks, can improve (decrease) blood pressure in patients with type 2 diabetes with uncontrolled hypertension who are on an angiotensin-converting enzyme inhibitor or an angiotensin receptor blocker. The safety of this treatment will also be studied.
